Dear list,
I have to do an ANOVA analysis with one fixed effect A and one random
effect SUBJECT. TO do this I used aov in the form
> aov.m1 <- aov(depvar ~ A + Error(SUBJECT/(A)));
My question is if I obtain significant differences within the strata,
does it make any sense to make multiple comparisons in order to know
what levels of the factor are significant?. I asked this because I get
an error when I try
TukeyHSD(aov.m1), and I am not sure if this is correct.
thanks
